GLASS WORKS. OF CORNIN G, NEW YORK, A CORPORATION APPARATUS FOR sHArnr'o oLAss ARTICLES.

Application filed December 10, 1923. Serial No. 679,765.

To all 'IUIIO'IIL'iZ may cancer-iv:

Be it known that we, DAVID GRAY, HARRY R. BOALS, and JAMES -BAILEY, all citizens of the United States of America, and all residing at Corning, in the county of Steuben and State of New York, have jointly invented certain new and useful Improvements in Apparatus for Shaping Glass Articles, of which the following is a specification.-

This invention relates to an apparatus for shaping-glass, and it has'particular relation to means for altering the shape of adesired portion or portions of articles which have been given a preliminary shape.

Among the objects of this inventionare to provide meansfor holding the article while means for imparting the configuration of the shaping member to the heated portion of the article, and a common means for controlling the heating means and the shaping means, as will be hereinafter pointed out /and claimed. I,

In the present application, by way of illustration, we have embodied our invention in an-apparatus for forming lips on beakers, although it is not/limited to this purpose.

In the accompanying drawings forming part of this specification A .Figure 1 is a side elevation, partly in seea burner playing on the article to be treated;

Fig. 2 is a similar side elevation, but showing the shaping block raised to its functioning position, and the finger making the-lip on a beaker, the burner arm being omitted to more clearly show the remaining parts,

Fig. '3 is a plan View of the machine in the position shown in Fig." 2. 4

Referring to the drawings, 1 is the base for the machine on which is mounted the upright 2, which carries a bracket 3, adjustable in height by locking screws 4. A sleeve 5,

rotatably mounted on the upright 2, has attached to it by the hinged joint 6, the operating lever 7. ()n the upper end of the upright 2 is the collar 8, held by the set screw 32.

Adjustably fixed to the sleeve 5 is the burner-carrying arm-9, the arm being angularly disposed, as shown, in respect to the operating lever. Theburners-IO and 11 carried by this arm are adjustable in direction, the one burner 11, being so directed in one angular position of the sleeve as to throw sis flame on the outer wall of the: upper portion ot' the article held in the chuck 23 (to be described later) while the other burner 10 is directed so that in the same position of the sleeve it throws flame on the inner'surface of the article at the same point, but in a slightly downward direction (see.

Fig. 1-

The burners 10 and 11 may be laterally adjusted by the thumb nuts 12 and 13, and may be also adjusted vertically ahd in inclination by the'collars 14 and 1,5, carried respectively by the downwardly projectingarms 16 and 17 from the burnerarm 9.

. The article to be treated is held in the chuck 23 byvacuum when the vacuum line 2% isopened at the valve 25. Running through the base 1 and theend of the bracket 3 is the adjustable push-rod 18,

which, on being depressed, tilts the lever'21. The outer end-of the lever 21 is bifurcated,- the arms thereof being pivoted to the lower.

ends of the rods 22, the upper ends of which carry the shaping block 19, thereby lifting the block from-its usual position in Fig. 1,-

up and adjacent to the upper end of the artic'le, (see Fig. 2). The former '19 is ad-' just-ably connected to the rods 22 by the set screws 35.

The operating arm 7 carries on' its,outer end a telescopic extension 27 terminating in a handle 28. In the telescopic extension piv- V oted at 31, is the upper end of the finger 26,

which acts as a wiper and may be of'any desired shape or size, and is normally held at right angles to the arm, by the spring 33. The operating arm 7 is normally held elevated on its pivot 6 by a flange 30 on the bracket 3, but may be lowered when over the chuck, the flange 30 being cut away at I 34 to permit this. 7

The article. 29 to be treated having been put in the chluk 2?),"is held thereby vacuum when the valve 25 is opened. With the parts in the position shown in Fig. 1, burners 10f and 11 will play on 'and heat a portion on the edge of the article to the. desired temperature. The operator then swings the operatin lever 7 angularly over the cut away portion 34 of the flange 30, and then depresses the lever. The first movement moves the burner-earning arm 9 away from the ar tide, and places thetine'er 2G thereover, and the latter movement depresses the push-rod 18 to lift the shaping block 19 to a, positionadjacent the heated surface of the article, and inserts the finger 26 withinthe article. The operator then pulls the handle 28 and the linger is brought into contactwith the heated zone of the article ata point adjacent ito the shaping block if), and ipushes or wipes the glass into theshaping block with a prcs sure deterlii iied by the spring 33 shaping 1 a portion of the article into. a lip' or ,other desired contiguration determined by the shape of, the shaping block and finger. I "The above operations finish the articlo to the desired shape and it is then only necessary to unloadthe niaehine,and replace the finishedarticle by anew article to be treated. To accomplish this, the handle 28 returned to its original position. which allows the spring 33 .to-l'uinQ; the finger 26 to its vertical p ositiou.. ()n raising the lever T by the handle 28, pressure is ren'ioved trom the push-rod 18. and the shaping block 19 drops down over the chuck 23, out of operating position on the bracket 20. Lever 7, on being raised as stated above, out of the cut-away portion 34: of the-flange 30, can'be moved laterally in either direction so that neither burners uorlever will be directly oter the chuck. In this position a new article can be inserted, and on moving the lever 7 laterally ole, starting the cycle of operations over again. 4 Y

While the particular embodiment of our invention disclosed herein is adapted. for lipping beaker-s, we desire to have it understood that our invention is susceptible of many other uses within the scope of the following claims. N v
